Title: Add gmail-backup.

gmail-backup is kind of funky. It's a Python script, and it's designed to be
run from within its source directory. It also appears that it's not intended to
be installed so much as unzipped and left somewhere. That said, it's quite
useful, and I don't know of a good alternative.

Let me know if there's a better way to write this formula.
